If you are not sure about your current transaction mode, you can use the "SELECT @@AUTOCOMMIT FROM DUAL" statement to find out as shown in the following tutorial exercise:

mysql> SELECT @@AUTOCOMMIT FROM DUAL;
+--------------+
| @@AUTOCOMMIT |
+--------------+
|            1 |
+--------------+
1 row in set (0.00 sec)

mysql> SET AUTOCOMMIT = 0;
Query OK, 0 rows affected (0.03 sec)

mysql> SELECT @@AUTOCOMMIT FROM DUAL;
+--------------+
| @@AUTOCOMMIT |
+--------------+
|            0 |
+--------------+
1 row in set (0.00 sec)

mysql> SET AUTOCOMMIT = 1;
Query OK, 0 rows affected (0.00 sec)
